The Water is ejected by compressed air, the ejector being put in action bythe movement of the same lever Which releases the torpedo in such a manner that as soon'as the torpedo is released the water is ejected from uoyancy unchanged.

If the boatsl are provided with two torpedo has been released, thus leaving the pedofw'ells only, the wells are situated on thel center-lineof the boat'.

24 is the electric motor for propelling the boat'when submerged, the said motor being preferably a dynamo, sonas to enable it to be usedvfor charging the accumulatore 25 when the boat is stationary. H i 26 is the oil or spirit motor for propelling` the boat When not submerged. .27 is the tank to contain the oil or spirit for the motor 26.

28 is a spur-Wheel running loose on the propeller-shaft 29, and is a spur-wheel also running loose on the shaft 29.

The Wheels 28 and 30 are capable of being locked to the shaft 29 b y the sliding clutch 31, the clutch being so arranged that when one wheel is locked to the shaft the other Wheel is free, or both Wheels may be free at the same time,although it is impossible to lock both wheels at the same time. The Wheel 28 gears with a pinion 32, which runs loose on the shaft: 33, the said pinion being locked to the shaft when required by the sliding clutch 34. vThe wheel, 30 gears with a pinion on the crankshaft of the motor 26.

When the wheels 28 and --30 are un locked from the shaft 29 and the pinion 36 is locked to the shaft 33, the motor 26 may be used to drive the dynamo 24 to charge the accumulators 25, or the dynamo may be used to start' the motor 26.

In order to allow the whereabouts of a submarine boat which has been accidentally sunk, or which is from any other reason unable to rise to the surface, to be at once indicated, I

form Wells 37 and 38 in the boat, in Which' wells are secured buoys 39 and 40, the buoys being-automatically released when the boat sinks too far below the surface of the waterinthe case of accident, for example. Attached to each b uoy is an india-rubber or other suitable tube 41, the other end of the said tube being;r attached, to the bottom of the scenes Well orfto the hull of the boat, "the inboard opening being'closed by a, suitable valve 42. The tubes are coiled down in the vwells and afford a means oftcommunication between the interior of the buoys and the interior of the boat.; l At the top 'ofeach buoy is a flap or other suitable-valveopening inward, the

said valves being normally closed *by `airpressure, compressed air'being pumped intothe buoy and tube for this purpose.'

stufiing-box 46 and engaging with a recess inA the bracket or lug 47 48 is an unequal-armed levei` pivoited at 49 to the bracket/ 50, the long arm of thelever bein suitably attached to the boltI 44 and the s io'rt arm having anarmature lthereon.

52 is a horseshoe-electromagnet, which When energized. attracts the armature"51 and withdraws the bolt 44, thus releasing the t buoy 39.

53 is a manometer-tube containing mer, cury in metallic connection With the Wire 54 from the magnet-coils. mercury contains a terminal 58, connected to the batteryw ire 55, theother battery Wire 56 being connected with the magnet-coils.

57 4is a battery which may be one or more of the accumulator-cells 2 5.

When the boat reaches a predetermined depth from any cause, the pressure of the'water forces the mercuryin the manometer u'p ward until it .comes in contact withfthe terminal 58. The current then passes from the battery, through the 'magnet -coils and manometer, energizing the magnet 52,Which attracts the armature 5l, moves the lever 48, withdraws the bolt 44, and releases the buoy, or the Wells may be fitted with airtight covers held in place by exhausting the air from the Wells. As soon as the boat sinksbelow a certain depth the pressure of the water bursts the covers, which then floatolf,1and the buoys rise to the surface.

When a buoy is released, it immediately rises to the surface of the Water. The valve at the inboard end of the tube is then opened. The compressed air/in the buoy escapes. The flap-valve opens'and allows freshair to enter the boat.

The space abo've the Conversation mayl be carried on by means of the tube between the crew of the submarine and people above. A

To the bottom ofthe boatl attach suitable fixings 59, the upper part of the said fixings being secured to the bottoms of the buoy- Wells 37 Attached to each xin'gwitlnn pur ose, the buoyant torpedoes arey fitted e with it.

j eye is a line 61 to serve to retain the buoy and to act as a guide for the divers engaged.

in salving operations. v'As the line is somewhat shorter than the tube 41, it serves to relieve the strain on the tube when a buoy is released.

The boat is .itted with the usual water-ballast tanks for diving and other purposes and with the necessary ejectors for emptying the tanks or some of them.

When a boat is to be used for placing submarine mines in a field for defence or other wit v a device for causing them to explode on contact with a passing vessel. The torpodoes are also fitted with a line and sinker. The line, which is of the proper length, is coiled down in the well with the torpedo, the sinker being on the outside of the hull. As soon as the torpedofiis released the torpedo rises and uncoils the line. The sinker, beingl no longer held by thejtorpedo, lfalls and sinks and When the line-is taut carries down the torpedo What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a submarine boat the combination pedoes, wells in which are carried buoys to indicate the position of the boat if sunk, said buoys being automatically released when the boat sinks below a certain depth, an eXtensi-` ble spar torpedo fitted in the bow of the boat,

name to this specification in the a grapnel normally housed in a chamber at the bottom of the boat for securing and cutting the cables connected to submarine boats, and means for propelling and submerging the boat, all substantially as specified.

2. A submarine boat provided with means for submerging and propelling same, Wells in which are carried buoyant torpedoes and buoys for indicating position of boat if sunk, means for holding the torpedoes and buoys inthe wells and means for launching the torpedoes and releasing said buoys operated by release-levers within/ the boat substantially as shown and described.

3. In a submarine boat provided with wells in which are carried buoys for indicating the position of the boat if sunk, a valve opening inward in the top of the buoy, a tube connecting the inside of the buoy with the inside of the boat, a ring at the bottom ofthe buoy, a bolt passing through said ring, a lever attached yto said bolt, an armature secured to shortarm of said lever,.'an electromagnet which attracts said armature when energized and an electric battery and a manometer to close the electric circuit when the boat reaches a predetermined depth as and for the purpose specified.
